ProFTPD module mod_qos
ProFTPD module mod_qos
The mod_qos module can be used to set the Differentiated
Services field (RFC2474)
of IP packet headers. This can dramatically aid in the handling of these
packets in the network, depending on the network QoS configuration.
This module is contained in the mod_qos file for
ProFTPD 1.3.x, and is not compiled by default. Installation
instructions are discussed here.
The most current version of mod_qos is distributed with
the ProFTPD source code.
Directives
Syntax: QoSOptions "ctrlqos" value|"dataqos" value
Default: None
Context: server config, <VirtualHost>
Module: mod_qos
Compatibility: 1.3.4rc1 and later
The QoSOptions directive configures the QoS bits to use for
the control and/or data connections.
The possible values to use are:
- cs0
- cs1
- cs2
- cs3
- cs4
- cs5
- cs6
- cs7
- af11
- af12
- af13
- af21
- af22
- af23
- af31
- af32
- af33
- af41
- af42
- af43
See RFC2474 for a better
discussion of these values.
Note that while the following values are also supported, their use is
deprecated, and can have adverse effects on TCP congestion control:
- lowcost
- lowdelay
- mincost
- reliability
- throughput
For including mod_qos as a statically linked module in your
proftpd, use:
$ ./configure --with-modules=mod_qos
Alternatively, mod_qos could be built as a DSO module:
$ ./configure --enable-dso --with-shared=mod_qos
Then follow the usual steps:
$ make
$ make install
Alternatively, if your proftpd was compiled with DSO support, you
can use the prxs tool to build mod_qos as a shared
module:
$ prxs -c -i -d mod_qos.c
